\ SAFETY ATTACHMENT FOR GAS BURNERS. I,

Application filed May 22, 1925.

To all whom it may concern:

Be it known that I, JosErH A. HALLER, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented new and useful Improvements in SafetyAttachments for Gas Burners, of which the following is a specification.

Owing to the particular construction of the valve operating handles ofgas stoves, numerous accidents occur in opening the valves at theimproper time and allowing the escape of gas which not only wastes: thegas, but tends to nauseate any occupants of the room, and furthercreates considerable hazard in case of the striking of a match or themaking of fire in the room. before the gas has been dissipated.

The object of this invention is to provide a simple, inexpensive andeasily app-lied attachment which may be applied to the valve structuresof gas stoves or analogous burners, and will prevent accidental turningof the valve handles and-the resulting opening of the valves and escapeof imignited gas.

More specifically, the invention relates to an attachment made of springsteel or other suitable metal which may be clamped upon the body orbarrel of the valve and engages against the stop pin of the valve conefor preventing accidental turning of the valve, it being necessary tofirst spring the safety attachmentout of engagement with the pin topermit the valve to be opened.

Other objects of the invention will appear in the following detaileddescription, and in the accompanying drawings wherein:

Figure 1 is a side elevation of a gas burner valve showing the improvedattachment applied.

Figure 2 is a top plan of the improved attachment showing it applied toa fragment of a gas burner valve.

Figure 3 is a side elevation of the attachment.

Figure 4 is a top plan of the attachment.

Figure 5 is a side elevation of the attachment taken at right angles tothat shown in Figure 3.

Referring more particularly to the drawings, the improved attachment isshown used Serial No. 32,153.

in connection with a gas valve of approved type embodying the barrel A,operating handle B, and stoppin G which is carried by the rotatablevalve cone D and engages against the shoulder E to limit the movement ofthe valve cone. The attachment which is preferably constructed of springsteel or analogous material comprises a split collar 1 having paralleltransversely extend ing ears 2 thereon through which a clamping bolt 3extends. The collar 1 is clamped by means of the ears 2 and bolt 3 uponthe neck F of the valve barrel or body A. A tongue 4 is formed on thering 1 and projects downwardly and inwardly therefrom for engagementwith the barrel A of the valve structure to prevent rotation of thecollar 1 upon the neck F. The ring 1 has an upstanding ear 5 formedthereon to which is attached the resilient arm 6. The arm 6 is bowedoutwardly from its point of attachment with the ear 5 and is bentstraight inwardly providing the straight portion 7 and the thumb portion8 which extends at right angles to the straight portion 7. The thumbportion 8 curves outwardly and downwardly from the upper outer corner ofthe straight portion 7, as clearly shown in Figure 1 of the drawings,and provides a shoulder 9 at the end of the straight portion 7 whichengages the stop pin 0 for preventing rotation of the valve cone D. Thecurvature of the body 6 and its inherent resiliency cause the shoulder 9to spring inwardly into engagement with or into the path of the pin C,and to rotate the valve for opening or permitting the flow of gastherethrough, it is necessary to force the shoulder 9 outwardly,

tensioning the body 6, by pressure upon the thumb portion 8, thus itwill be seen that accidental opening of the valve will be impossible.

It is, of course, to be understood, that the invention may beconstructed in various other manners and the parts associated indifferent relations, and therefore, I do not desire to be limited in anymanner, except as set forth, in the claim hereunto appended.

What I claim is The combination with a valve structure including a body,a rotatable valve and a stop pin for limiting the rotation of the valve,of a resilient body having a straight portion terminating in. a shoulderfor engagement With said stop pin, a thumb portion projecting at acuteangles from the straight portion vto permit the shoulder to be sprungout of the path of the pin a split ring attached to said resilient bodymember and adapted to clamp about a portion of the valve body, and atongue formed on said 10 ring and engaging the body to prevent movementof the ring relative to the body. In testimony whereof I affix mysignature.

JOSEPH A. HALLER.
